[23] THE SCHOONER GRAMPUS. 459 



The hand-power or pump brake arrangement for working the wind- 

 lass when steam was not used was so arranged that it could be geared 

 to obtain different degrees of purchase power. 



The weight of the windlass and engines (exclusive of the 24-inch 

 gypsy ends) was 5,800 pounds. The gypsy ends had a combined weight 

 of 1,000 pounds, making a total weight, including these, of G,800 pounds. 



As has been stated elsewhere, the steam windlass was removed after 

 the vessel made one trip and replaced by a common wooden pump- 

 brake windlass, of the typo used on fishing-vessels of the same size. 

 This windlass is 19 inches diameter in the middle, 14 inches on star- 

 board barrel, and 22 inches on port barrel, over whelp. It is arranged 

 for chain on the starboard side, and is fitted with a hard-wood jacket or 

 smooth whelp on the port side for the steel hawser, which is generally 

 used, though it is also adapted to a chain-cable.* 



9. STEAM BOILER, FORCE PUMP, CONDENSER, ETC. t 



A 20 horse-power Brayton patent coil boiler was used for operating 

 the steam windlass. This was 6 feet high and 5 feet in diameter; pro- 

 vided with an adjustable pipe or smoke-stack, 1 foot in diameter and G 

 feet long, made in two lengths so that it could be shortened or re- 

 moved altogether, as occasion required. There was a brass deck-plate 

 for this pipe to pass through, and this was provided with a water-tight 

 brass cover that was put on when the pipe was taken off. 



The boiler was located between the well and the forecastle ; it was 

 connected with a Knowles combined vacuum and force-pump (located to 

 starboard against the ceiling) and with a keel-condenser. The latter 

 was made of heavy 2J-inch seamless brass tubing, and was 28 feet long 

 outside of vessel — 14 feet on each side of keel, through which it passed. 

 The 2J inch pipe began at boiler-room deck (floor of fore-hold) inside 

 of the vessel, and continued of that size until it passed through the 

 keel and returned to enter the vessel on the port side, where its size 

 was reduced to 1£ inches diameter for suction-pipe of vacuum pump, 

 and continued of that size above boiler-room floor. 



There was a brass sea-valve of 1 J inches diameter, fitted with strainer 

 over its end. 



The requisite piping for connecting the boiler with the steam-engine 

 passed through the forecastle bulkhead to starboard of the stove, 

 thence under locker seat to engine. 



10. CHAIN STOPPER. 



One of the Emery and Cheney patent elastic chain stoppers is lo- 

 cated close to the hawse-pipe on the starboard side. 



* The windlass originally put on the Grampus was transferred to the U. S. Fish Coin- 

 mission steamer Fish Hawk. 



t These were all removed when the steam windlass and engines were taken off the 

 vessel.
